IMPROVEMENT IN SPRING-MOTORS.

Specification forming part of Letters Patent No. 176,203, dated April 18, 1876; application tiled August 26, 1875.

To all whom it may concern Be it known that I, DAVID SHIVE, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in a Spring Power or Motor; and I do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawings, making a part ot' this specification, in which- Figure 1 is a side view of the device embodying my invention. Fig. 2 is a central longitudinal section thereof. Figs. 3 and 4 are edge Views ot' the spring.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in a combination of springs in such a manner that the power of one spring only, or equivalent of' such power, is given out7 but the power is continued and lengthened in time as the number of the springs.

Referring to the drawings, A represents an arbor, which is mounted on bearings B B', and constructed in sections a I) c, which are fitted to each other by pin and socket joint-s d. On the arbor A there are mounted barrels C C', which are separated from each other, and each barrel carries two springs, which The spring D of the barrel C is connected at one end by a stud or pin, a', to the section a of the arbor A, and at the other end to a stud or pin, c, at or near the circumference of the barrel. rlhe spring D is connected at one end by a stud, or pin, b', to the section b of the arbor A, and at the other end to the stud or pin e. The spring D is connected at one end by a stud or pin, b", to the section b ot' the arbor, and at the other end to a stud or pin, f, at or near the circumference of the barrel O. The spring Dlll is connected at one end by a stud or pin, c', to the. section cof the arbor, and at the other end to the stud or pin f. A ratchet and pawl will be fixed to the first section of the arbor and its bearing for sustaining the winding of the spring.

The operation is as follows: The winding by the crank ot' the section a and spring D does not in a direct manner wind the sections b and c7 but the winding of the sections b and c is effected through the winding of the springs, which wind alternately in opposite directions. The windin got' the section a winds the spring D from a to c. The spring D, being attached to the barrel U at c, causes said barrel to turn. This causes the spring D' to wind from c inward to b upon the section b. Section b being turned, winds the spring D" from b tof, which, by turning the barrel C', winds spring D upon the section c, which imparts power of all the springs to gearing attached to the section c.

Washers g are placed between` the springs, and t neatly in the barrels and around the arbor. The heads ofthe barrels also tit neatly around the arbor, and by these means and the pin and socket joints of the different sections of' the arbor the whole is firm and steady in line.

The object in having a firm barrel with two heads, and the heads fitting neatly around the arbor, is, first, to secure a free and easy motion to the two springs therein contained, which, without such barrel, would have a diagonal and binding motion, owing to the springs being placed alongside of each other; secondly, to secure a bridging and strength to the arbor which otherwise would require a support through the center, thus occupying the best place for the spring.

The washers separate the springs and impart strength and support to the arbor where joined.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A series of springs winding in reverse order, in combination with an arbor formed in sections, substantially as and for the purpose set forth.

2. rIhe barrels O C, inclosing the springs, and mounted on the arbor A, which is constructed in sections a. b c, fitted together by pin and socket joints d, substantiallyas and for the purpose set forth.

3. The combination, with the barrels C C', of the washers g, interposed between the springs in said barrels, substantially as and for the purpose Set forth.

DAVID SHIVE.
